The MCP6041/2/3/4 op amps’ Common Mode Input
Range, which goes 0.3V beyond both supply rails,
supports their use in high side and low side battery
current sensing applications. The very low quiescent
current (0.6 µA, typical) help prolong battery life, and
the rail-to-rail output supports detection low currents.

circuit. The 10Ω resistor is sized to minimize power
losses. The battery current (I
resistor causes its top terminal to be more negative
than the bottom terminal. This keeps the common
mode input voltage of the op amp below V
within its allowed range. The output of the op amp will
also be below V
